[Paraview] Gradient filter

[Thorsten Hater]

Hello,

I have got some problems with the ParaView gradient filters.
Applied to my datasets they crash ParaView both 3.0.2 and 3.1.0.
This comes in two variations:
1. if I read my data directly and apply Gradient to it, ParaView crashes 
(segfault)
2. if I read my data, save it and read it again ParaView crashes when I 
delete the dataset
after applying Gradient ("double free or corruption")
I'm using pvti files with GhostLevel="2" but this happens on the 
underlying vti files
as well.
Can anybody tell me something about this problem?
